SPRING-VEHECLE.

SPECIFICATION forming part of Letters Patent No. 331,334, dated December1, 1885. Application filed August 26, 1885. Serial No. 175,389. (Nomodel.)

To all whom it may concern.-

Be it known that I, OYRUs W. SALADEE, a citizen of the United States,residing at Shelton, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inVehicles, of which the following is a specification.

My invention relates to that class of vehicles in which longitudinalsprings support the body; and my invention consists in constructing andconnecting the springs, as fully set forth hereinafter, so as to securean easy elastic support, prevent side motion and the turning of theaxles, and generally improve the spring-platform.

In the drawings, Figure 1 is a perspective view of the running-gear of abuggy illustrating my invention. Fig. 2 is a perspective rear view ofthe front axle. Fig. 3 is a plan View of the gear with the body andwheels removed. Fig. 4 is a detached side elevation of the yoke to whichthe front ends of the perchsprings are connected. Fig. 5 is a sideelevation of the wagon. Fig. 6 is a plan view of gear, showing amodification. Fig. 7 is a side elevation of one of the side springs,showing one form that may be used.

' In carrying out my invention I use the usual front axle, J, rear axle,K, front bolster, I, two parallel springs, a a, on the same horizontalplane, constituting together the central springreach, B, andlongitudinal side springs,A,each of which may be single or duplex incharacter, the reach and side springs being all of the same length, andcurved so as to operate properly in unison. The central portions of allthe longitudinal springs are rigidly connected by cross-braces O G.

In the construction shown in Figs. 1 and 2 each side spring, A, is asingle spring; but in that shown in Fig. 6 each side spring, A, consistsof two similar springs, 12 b, on the same horizontal plane, and D D areclips secured to the ends of the bolster and rear axle, and eachprovided with an eye receiving a transverse bolt, E, that supports theends of the adjacent springs 11 I), connecting them, but preserving themat their proper distance apart. When the duplex springs are used with arigid frame-gear, their ends may be supported by links hung to theframe. The rear end of the duplex-spring perch is carried by a bolt, E,supported by a hanger, H, pendent from the rear axle, and integraltherewith or secured thereto.

S, Fig. 4, represents a yoke, to which the front end of theduplex-spring perch is connected. The yoke has an eye, H, integral withthe main body of the yoke, which latter is extended and bent up toconnect with the rear side of the bolster at S. The front end of theyoke is supported in relation to the bolster by a bracket or hanger, IF,the upper end of which is attached to the bolster at 8*, and its lowerend passes through the yoke. A king-bolt, V, passes down through thebolster and axle and the yoke,as seen in Fig. 4..

T represents the body, which is supported by cross bars or stays restingon the side springs.

By making the side and reach springs all of the same length, and so asto act in unison with like efi'ect, which latter result is best attainedby making them all of the same curvature, I prevent the vibration of thesprings from causing any rotation of the axles, and by connecting allthe springs at the centers I stay the body against side or tippingmotion when the load is on one side.

WVhen the front and rear parts of the frame are connected by a singlespring, or two springs, one above the other, centrally arranged, thespring has no effect in tending to keep the other parts in theirposition at right angles to it; but when two springs are arranged sideby side, each connected at each end to the frame and connected centrallytogether, the springs act effectively to stay and brace the front andrear parts and maintain them in their required positions without the useof the ordinary axlestays. The duplex-spring perch also insures greatstrength, a security against accident, should one of the pair befractured, and, in combination with the side springs, insures a soft andeasy motion to the body, as well as imparts to the complete structure afinished and elegant appearance.

hen duplex springs are used for both the perch and the side springs, asshown in Fig. 6, the lateral distribution of the steel admits of thinnerplates than where single springs are employed in the usual way for boththe side springs and center spring-perch, and hence a softer motion issecured, while the carrying capacity remains the same in both cases;and, besides, greater security against accident is assured, since eachspring is duplicated, and the one spring of each pair is a support andbrace to the other as well as to the entire structure. I

It will be understood that the arrangement of duplex side springs seenin Fig. 6 of the drawings may as well be applied to vehiclegears havinga rigid perch or perches connecting the axles as in combination with thespring-perch shown in the drawings.

All the springs may be semi elliptical springs, as shown in Fig. 7, orthey may be of any other suitable forms.

When duplex side springs are used, the body may extend over and bebolted to the inner spring of each pair only, as shown in dotted lines,Fig. 6, thereby permitting the side springs to be placed farther fromthe center, securing a wider spring-platform and better support.Moreover, as the weight is increased the inside spring closes up againstthe bottom of the body, and thereby becomes stiffer as it is distended.

Without limiting myself to the precise construction and arrangement ofparts shown, I claim--.

1. In a roadwagon, two similar springs extended to connect the axles orbolsters, said springs being arranged longitudinally side by side on thesame horizontal plane throughout their entire length, and having theiropposite ends carried upon a single trunnion pin or bolt supported bythe frame, substantially as described.

2. In a road-wagon, a spring-perch consisting of two similarflexion-springs arranged side by side, extended to connect the axles,and having their center portion rigidly secured in respect to the bottomof the body, substantially as described.

3. The combination, with the perch consisting of similar springsarranged side by side, of side springs and central connections betweenthe side springs and the springs of the perch, substantially asdescribed.

4. The combination, with a duplex-spring perch consisting of two similarparallel springs side by side, of the upper side springs, A A, and.transverse connections, substantially as described. 5. The combination,with the rear axle, the suspended arm H, and rear springs, a a, of theduplex-spring perch B, substantially as described.

6. The yoke S, connected to the front bolster and interposed between theparallel springs a a, composing the spring-perch, substantially asdescribed.

7. The eyes D D, interposed between the duplex side springs, b b,substantially as described.

8. The combination of the frame, side springs consisting each of a pairof springs arranged side by side, and a body extending over and securedabove the inner spring of each pair, the outer springs being beyond thebody, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
